The NOAA Ocean Exploration and Research team recorded a school of deep-sea dogfish feasting on a dead swordfish about 1,476 feet below the surface off the coast of South Carolina. The video shows at least 11 of the sharks devouring a recently dead 8-foot swordfish.

Then comes an even bigger surprise.

A bony fish known as a wreckfish comes from behind the researchers’ remotely operated vehicle and snatches a shark into its mouth, leaving only the tail flailing between its lips.

It’s rare to see sharks like this in a group

The NOAA team said it’s uncommon for deep-sea sharks to be in a group unless there is some nearby patch of food.

Peter Auster, a senior research scientist at the Mystic Aquarium and research emeritus professor at the University of Connecticut, said these sharks probably traveled a long way to feed on this swordfish. Scientists call this a “food fall.”
